Abstract
The invention relates to a coated glass substrate, covered with at least one thin layer based on silicon nitride or silicon oxynitride. The thin layer contains the elements Si, O, N, C in the following atomic percentages: PA1 Si: from 30 to 60%, PA1 N: from 10 to 56%, PA1 O: from 1 to 40%, PA1 C: from 1 to 40%. The invention also relates to the process for obtaining the coated glass substrate using a gas-phase pyrolysis technique, and to its applications.
